Patented Dec. 3, 1907.

Be it known that I, CHARLES "1. TOLMAN, a citizen of the United States,residingiat New York city, in the State of New York, have invented a newand useful Graduated Measuring-Can, of which the following is a Ispecification. y

My invention relates to improvements in cans, -particularly to oil cans,from which a redetermined uantity ofoil may be deivered 'or supp ied toany desired point. In lubricating car journals it is generally desirableto deliver to each journal the same quantity of lubricant in order toprovide uniform lubrication throughout. It is also desirable to have acan from which lubricant cannot flow by gravity until the point to whichit is to be delivered shall be in communication with the reservoir,thereby pre'- venting waste of fluid and insurin the delivery of thedesired amountof iuid to the desired point. Another desirable featureina can is means for enabling the operator to rapidly handle heavy or-Slow flowing fluids to be discharged therefrom. `It is also convenientor necessary at times to deliver a fluid to a'large number of places inequal quantities, as in the use .of a liquid fertilizer or the like,where it is desirable to deliver. the same quantity of liquid to a largenumber ofv laces.

p My invention as for its object the provision of means for deliveringfrom a suitable reservoir to any desired point oil 40r .other fluid' inpredetermined equal quantities so Vas to' make effective,Y among others,the

various desirable features above set forth, and -to overcome the manydefects now existing in cans for similar uses, and my invention consistsin the novel construction, arrangement and combination of devices andparts as hereinafter more fully described and lset forth.

In the drawings Figure 1 shows a vertical cross-section of the device;Figs. 2, 3 and 4 modifications of the means for adjusting the stroke ofthe'piston for discharging the iiuid.

Similar numerals of reference indicate similar parts throughout thedrawings. Referring to the Adrawings, a reservoir. 1 ofanysuitablestructure is preferably provided with a hand/le 32 and bail 31,so that it may be portable. A stationary handle 19 suitably attached tothe reservoir obviously serves to enable the operator to tilt or invert`mounted on the to said barrel having 1n 'communication wit and anoutlet ordischar e pipe 5 which 60 carries any form of disc arge nozzle4..

it a suction pipey 23,

Said suction pipe 23 is provided with a suction valve which may belocated at any Vconvenient place in said pipe, but preferably at itslower extremity. Said suction valve consists of a valve 25, a casing 24.attached to the pipe 23 and in which is provided the seat for valve 25.A guide 26, preferably provided in the suctionpipe 23, ycarries the stemof the valve 25, and a spring 27 tends 7b to hold said valve on its saidseat. Within the discharge pipe 5 or nozzle 4 is located a dischargevalve 29 having its stem preferably guided by a shoulder on the interiorof the inclosing-case and having a seat 39 and a 75 suitable spring 30which tends to hold said valve on said seat.

' Operative within the barrel 2 is a piston consisting of guides 8 and36, packing 6 and 7 to insure tightness in both directions, and 80packing followers 9 and 10, said guides 36 be- 4 ing held a suitableldistance from the piston proper by distance piece 11, all said partsbeing held together by bolt 13, the bolt being securely screwed intoguide 36 and into lug 85 12. A spring 28 of suitable strength ispreferably provided within the barrel 2 which acts between the pistonhead and the end of the barrel and tends always-to maintain the pistonin the position shown in Fig. l, with the guide 36 abutting againstbarrel head 3, or it restores the piston to this position in the barrelafter the same has .been displaced as hereinafter described. Pivoted tolug 12 by a pivot 16 is a connecting link v14, the other end 95 of saidlink being provided with threads -or lotherwise adjustably attached tolink 15 atV one end'thereof. The other end of said link l5 is pivotallyattached by pivot 17 to a movable or. supplementary handle 18, saidhandle beinlgl pivotally attached by pivot 21 to support 20provided onstationary handle reservoir for filling the same.

' 19. A suitable means 22 is provided in the',

It is evident that by the pressure of the hand on movable -orsupplementary handle 18 said handle 4can be forced into the dottedposition shown in Fig. 1.- This movementA of the handle is transmittedto the piston through the connecting links 14 and 15 and the variouspivots, and the piston thereby caused to move in barrel or cylinder 2.against .the pressure of spring 28.- Li'quid having been put into thereservoir through inlet 22, and the pumpcavities being full of liquid,the movement of the piston augmente the pressure in said cavities andmore securely holds suction valve 25 `on its seat and simulta- .neouslyraises discharge valve 29 in its seat against the pressure of spring 30,lpermitting escape of -the I fluid fromA the nozzle. As soon as thepistonv has reached the end of its discharge stroke, the augmentedpressure in the pump cavities is released and discharge valve 29 isseated by spring 30 cutting ofl' all further discharge of uid bygravity. When manual pressure is removed, spring 28 forces the pistonback tothe position shown in Fig. 1, and the vacuum created in the pumpcavities by the return of the piston to its normal position,causes'suction valve 25 to raise on its seat against the force of spring27 and permits the inlet of fluid from the reservoir to 'fiill the saidcavities.

It is further evident that the abutment of movable handle 18 againststationary handle 3,19, limits the stroke of the piston in the disi' so'charge of fluid from the cavities, and that the abutment. of guide 36against head 3 of the cylinder 2 limits the stroke of the piston in theintake of fluid. The length of connecting links 14 and 15 between pivots16 and 17, therefore, determines the length of stroke of the piston, andby adjustment of the stroke the quantity of fiuid discharged from thepump cavities upon each discharge stroke becomes fixed. It is evidentthat if it is desired to change the quantitiy of fluid to be. deliveredfrom the device,.-it is only necessary to remove either pivot 1 6 orpivot 1 7 and vary the effective length of the connecting rod byscrewing or unscrewing one link in the other.

Link 14 may be marked in graduations indi? eating the quantity of fluidwhich will be def livered when the links are adjusted'l at any one ofsuch graduations. A

It is obvious that the apparatus may be tilted to any angle Without theescape of any iiuid through the nozzle by gravity unless the piston'isforced against the ressure of the spring 28, since discharge va ve 29tends to always cut off all exit of fluid until it is lifted .from itsseat by the excess pressure due to the motion of the piston.

If it is desired to use the device for the discharge of a liquidfertilizer or disinfectant or for other similar uses,'it is onlynecessary to attach to the nozzle 4 any suitable spraying devtiice' fordistributing the 'liquidwhere desire It is'essential in cans of thistype to prevent vthe vexposure ofthe contents to air.

This is particularly true of oil since the latter oxidizes when soexposed. For this reason' it is desirable to place the discharge valveas near the outer end of the discharge cavity as possible, so that whenthis valve isclosed no oil will remain in the discharge cavity beyond`the valve to become oxidized by exposure to 'the air. .I show thispreferable situation of the discharge valve in thedrawings.

Another means for adjusting the length of stroke of the piston andthereby predeterinining the quantity of fluid to be delivered is shownin Fig. 2 in Which the rod 38 pivotally connecting lug '12 with movablehandle 18 is in ade in one piece, instead of in two links as in Fig. 1,and a stop 37 is inserted through a suitable opening in-head 3 of thecylinder and -made adjustable therein so as to limit the length 'ofstrokeof the piston in the suction or intake direction to anydesiredextent to determine the quantity of fluid to be delivered.

Another means for adjusting the length of stroke ofthe piston is shownin Fig. 3, in which I place theadjustable stop -37 in the movable handle1-8 instead of in the cylinder head 3 as in Fig. 2. In this case thestop,

j when it abuts handle 19, limits the length of' the discharge stroke ofthe piston, as is the eiiect of the adjustable links 14 and 15 in Fig.'1, and consequently by adjustment dctermines the quantity of liquidwhich shall he discharged. A j

Another modification of the means for adjusting` the length of strokeofthe piston is shown in Fig. 4, in which I provide an adjustableconnecting device, 40, joining the piston proper and the'guide 36,consisting of a bolt 40 suitably attached to the piston proper andthreadedinto and through guide 36, and provided withalsuitable stop 41to prevent longitudinal motion of the piston proper on the bolt and alsowith nut 42 with which to adjust the relative position of the pistonproper and the guide 36 as desired.

Lug 12 may be attached to guide 36 orlto bolt 40 in any suitable manner.Connecting rod 38 is similar to that shown in Fig. 2. A

stop 43 fixed in the cylinder 2, or Which may .normal position, therebyassistin` inthe rapid handling of the contentsY ofie reservoirbyrelieving the operator of the necesmanner that convenience of use mayrequire.
